The utility model belongs to the spark ignition device that petrol engine is used in the automobile, and particularly a kind of mulitple ignition device of improved employing electronic circuit is applicable in the petrolic igniting of various models.
Existing " automobile igniter " that is applicable to that gasoline engine ignition is used (CN2058212U) is made up of following four parts: the vibrator circuit of (1) band boosting transformer; (2) the secondary square-wave voltage of boosting transformer is exported than High Level DC Voltage through current rectifying and wave filtering circuit; The elementary serial connection mutually of (3) energy-storage capacitors and spark coil, than High Level DC Voltage by a diode with spark coil is elementary charges to energy-storage capacitor; (4) controllable silicons are triggered the triggering with voltage on the coil, and the energy-storage capacitor that has charged is by the elementary discharge of controllable silicon and spark coil, so the secondary generation high pressure of spark coil makes plug ignition.The deficiency place of the prior art can only provide a spark when being each cylinder igniting.
Task of the present utility model is improved above prior art, can provide a plurality of high-energy sparks when requiring each cylinder firings of motor, make mixture combustion abundant, kinetic force improves, (15 ℃ to-30 ℃) also can start when low temperature, oil consumption and tail gas pollution also can reduce, and requiring in addition also can reliably working when the higher and ambient temperature of generator voltage is higher.
Task of the present utility model is finished as follows: design for convenience changes multi-vibrator by 1 kilo hertz of left and right sides oscillation frequency to the vibrator circuit of band boosting transformer in the above prior art and promotes two of a band boosting transformer and manage power magnification circuits and form.For being discharged and recharged, controllable silicon can produce the series high voltage pulse when firing circuit opens in the platinum contact, by another secondary trigger voltage that triggers about 1 kilo hertz of silicon controlled of drawing of boosting transformer.Certainly the parameter that controllable silicon discharges and recharges each element of firing circuit in the above prior art also adjusted.
Below in conjunction with accompanying drawing the utility model is further described.
